lMPROVEMENTIN WINDOW-SCREENS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom 'it may concer-n:

Be it known that I, JOHN HANCOCK, Jr., of the city and county of Providence, in the State of` Rhode Island, have invented a new and useful Improvement in Window-Screens; Aand I do herebyl declare the following is a full, clear, and'exact description thereof, reference lbeing had to the accompanying drawing andl to the letters of reference marked thereon, in whiclil-f A Figure l is a front View, showing the frame as in use.

Figure 2 shows the same when closed.

Myinvention consists in making a window-screen, the frame of which will remain extendedvvith` the cloth stretchedwvhen in use, and to fold with the cloth `rolling in one side in making it compact and portable.

To enable others skilled in the art to manufacture'I and use my invention, I will proceed to describe its construction and operation.` i i In the accompanying drawing- A A and B'B, figfl, represent the four sides of a screen-frame;` they are connected together at each end by a hinge onthc outside, and the sides B B are made each in two equal parts', and hinged at their centers on the inside, to be` operated outward in folding, and in connection with the corner hinges the 2. The upper side A is hollowed out and furnished with a roller,`having a string attached at one or each end, which operates similar to a common curtainroller. .To this Vroller is fastened one edge ofthe cloth, the opposite edge being secured to the opposite or lower sideA, which keeps the cloth stretched when in use, as shown in iig. 1.

On `the inside of B B is a groove for the selvedge edges of the cloth to slide in, making the screen tight against insects. c

When tted and in use the sides B B are kept from folding 'by the window-frame; the window or sash, resting upon the top side A, secures the screen in itsiplace.

Its simplicity and being compact when folded are its advantages. i

I do not claim-a screen or -the roller as my inven tion; but` What I do claim, and desire to secure by Letters Patent of the United States, is

The sides A A and B B, in combination with the roller, when constructed to operate substantially as set forth, and for the purpose speciiied.
